What type of jurisdiction allows both federal and state authorities to enforce law on an installation?

Concurrent jurisdiction refers to a situation where both federal and state authorities have the power to enforce laws within a particular area, such as a military installation. This type of jurisdiction is significant because it allows for collaboration and shared responsibility between federal law enforcement and state law enforcement agencies in maintaining order and ensuring compliance with laws. In the context of military installations, it means that both the military police and local law enforcement can operate and have authority to enforce laws, making it easier to address issues that might arise in these areas.

Exclusive jurisdiction would mean that only one authority, either federal or state, has the sole power to enforce laws, which is not the case here. Proprietary jurisdiction indicates that the federal government has the right to control the property but does not necessarily enforce laws as both federal and state entities can under concurrent jurisdiction. Federal jurisdiction is more broad and doesn't specifically address the relationship between state and federal enforcement on an installation. Thus, concurrent jurisdiction effectively describes the dual role of law enforcement on a military installation, allowing both federal and state authorities to work together.
